Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android. Quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs. Using this you won’t be editing any XML layouts or directly creating the UI widgets. Instead, you will call Jetpack Compose functions to say what elements you want, and the Compose compiler will do the rest.

The key component in Compose is Composable function. These functions let you define your app’s UI programmatically by describing its shape and data dependencies, rather than focusing on the process of the UI’s construction. To create a composable function, just add the @Composable annotation to the function name.
